The Milwaukee CD600 Digital Total Dissolved Solids (TDS) Pen is designed for hydroponics, aquariums, horticulture, water conditioning, and many other applications.
In agriculture, the CD600 helps to make sure that your plants are receiving the right amount of nutrient. For water filtration, this pen helps to make sure your filters are up-to-date and clean. Keeping TDS in your target range helps to achieve better results.
TDS/PPM electrodes can develop nutrient build up over time. To miminize build up, always rinse the probe in fresh tap or DI water after every use.
The Milwaukee TDS Pen, like all TDS meters, provides a measure of Total Dissolved Solids (ppm) reading, of contaminates per unit of volume in a solution.
TDS/PPM is often converted to uS/cm. Different scales include the 500 scale, 650 scale and the 700 scale.
Your TDS/PPM readings can be approximately converted to uS/cm as shown in the examples below.
1 ppm = 2 uS/cm on the 0.5 factor scale
1 ppm = 1.43 µS/cm on the 442 scale or .70 factor scale
Thank you for considering Milwaukee to help you take your results to the next level.
